In relation to GPS receivers, what is RAIM?
RAIM is a software algorithm that is available in some GPS receivers which gives an indication if the position accuracy of the GPS receiver is suitable for use. The RAIM availability (or ability of a GPS receiver to provide a RAIM warning) is dependent on the number of satellites available or in view by the GPS receiver. A minimum of five satellites is required to provide a RAIM warning. If there are less than 5 at any point in time at some location then this is identified as a RAIM hole (or RAIM unavailability). GPS receivers that also provide RAIM prediction do not take into account GPS satellites that have been taken out of service for maintenance by the United States Department of Defense.
